49 Arietis is a single[8] star in the northern constellation of Aries. 49 Arietis is the Flamsteed designation. It is visible to the naked eye as a faint, white hued star with an apparent visual magnitude of 5.90.[2] The star is located at a distance of about 223 light-years (68 parsecs) distant from Earth based on parallax.

This object is classified as an Am star,[9] or non-magnetic chemically peculiar star of the CP1[10] class, which means the spectrum displays abnormal abundances of certain heavier elements. It has a stellar classification of kA2hA6mA7, which means it has the calcium K line of an A2 class star, the hydrogen lines of an A6 star, and the metal lines of an A7 star. 49 Arietis has a moderately high rate of spin, showing a projected rotational velocity of 52 km/s, and is radiating 16 times the luminosity of the Sun from its photosphere at an effective temperature of 8,424 K.
